I am currently running windows 7 pro 64bit on my desktop. It is running fine, but I would like to take advantage of the free upgrade. My thoughts are as follows.
I have a spare 500gb SSD and was thinking of disconnecting my current SSD that has all my system and associated proggys on it, and putting in the spare, doing a fresh install of my Windows 7 on that and then doing the free update.
Hopefully once installed, I would have windows 10 on my spare SSD and can then disconnect it, re-connect my current setup and continue on.
Later on if and when I decide to go to Windows 10, it should be all setup. I assume this would be ok as it is all machine specific I believe.
Any reasons why this would not work..advice appreciated.
